备注

对焊接和螺栓连接混合的梁柱连接钢结构进行强度计算和力学性能分析.柱与梁的翼缘采用全熔透焊缝,柱与腹板采用高强度螺栓连接.通过计算焊缝和高强度螺栓连接强度,用来保证加劲肋和节点域符合强度标准,利用有限元软件对梁柱连接钢结构模型进行计算,获得相应的应力云图和位移图,并对其结果进行分析.

The strength calculation and mechanical property analysis of the welded and bolted joint steel structure are carried out.The flange of the column and the beam is welded with full penetration weld and the web is connected with high-strength bolts.The strength of weld and high strength bolt are calculated to ensure that the joints meet the strength requirements.Finally,through the use of FEM software to carry out stress and displacement analysis on the node model,the final analysis results are analyzed.
